hi and very pleased to answr you
If you do not forget taking the pill and do not vomit it, the pill will be effective at almost 100%.
The effectiveness of the IUD is about one
pregnancy per 200 women-year, I mean, if an IUD is inserted to 200 women, one from these 200 women will be pregnant in the year.
Occasional pregnancies develop even on a
uterus with a well-placed IUD.
For
hormonal IUDs, Spreading hormones for about 5 years, the risk of pregnancy is still lower, about one in 400, one in 500. It is a method that is very effective and gives a certain feeling of freedom. You can be sure for 5 years with an annual check.
The IUD does not increase the risk of ectopic pregnancy, but it does not protect against ectopic pregnancy. The diagnosis of ectopic pregnancy in a surrogate woman is more difficult because there is small bleeding.
Then, As I have just explained that despite the IUD, pregnancy is possible and as you have some symptoms that can refer to pregnancy, or even ectopic pregnancy (rarer), I URGE YOU TO CONSULT your gynecologist.
